Effect

This statement declares a general static method meth. The additions define make an interface method optional, define the parameter interface of the method, and specify the exceptions that the method can raise and propagate. The additions have the same syntax and meaning as those for general instance methods.

Notes

• Static methods cannot be redefined, which means that they cannot be flagged as abstract or final.
• Static methods are always executed in the class in which they were declared, even if they were called in subclasses or using the names of subclasses.
